Prof. Leanne Faulks of the Institute of Freshwater Biology presented at the 72nd meeting of the Ecological Society of Japan.

The Ecological Society of Japan held its 72nd conference in Sapporo from March 15-18, 2025. Leanne Faulks from the Institute of Freshwater Biology, Nagano University travelled to Sapporo to participate in a symposium titled Connectivity in river ecology: from genes to meta-ecosystem dynamics. Leanne presented the results of a research project that examined the influence of small weirs on fish biodiversity in streams around Ueda city. This study indicated that small weirs reduce fish movement and result in reduced levels of species and genetic diversity. Other speakers in the symposium also highlighted the importance of connectivity in watersheds for freshwater ecosystem function and biodiversity, including forest-stream linkages and freshwater-marine linkages.
